2 Claims. (Cl. 16-135) The present invention relates to improvement Another advantage of the invention is that it is scientifically designed with exacting proportions whereby the principal parts thereof may be composed of metal stampings, thus eliminating the necessity of castings and the like for this purpose, as in the commonly known hinges of this type.

*Still another advantage of the invention is the fact that the particular construction thereof permits a greater passage within the body entrance when the doors are open, 'or in other words, the

space is increased by approximately three inches greater than the corresponding space when the doors are open in the ordinary types of door hinges. I

It will become readily apparent during the course of the following detailed description and throughout the accompanying drawings, that the invention possesses advantages which are more fully pointed out in the appended claims.

With reference to the drawings:

Figure 1 is a partial exterior view of a vehicle body and pillar showing how it will appear with the improved hinges completely concealed and invisible from the exterior of the vehicle.

Figure 2 is a full size view of one member of the hinge with part thereof in section as indicated.

Figure 3 is a full size view of the second member of the hinge.

Figure 4 is a section taken along the line 44 of forthcoming Figure 9, and showing the hinge in a closed position of the door. I

Figure 5 is a similar section to Figure 4, but showing the hinge in an open position of the door.

Figure 6 is a vertical section taken upon the line 6-6 of Figure 4.

Figure '7 is a view in elevation looking at the inner edge of the door and showing the hinge members secured thereto.

Figure Sis a vertical sectional view takenv upon the line 88 of forthcoming Figure 9.

Figure 9 is a rear elevation of the assembly with the door broken away as indicated.

Figure 10 is a transverse sectional view taken upon the line Ill-l0 of Figure In further disclosing my invention, it is to be understood that certain elements directly associated with the same'but not a part thereof will be designated by consecutivealphabetical letters, while the invention proper will be characterized by the customary reference numerals.

The invention comprises a hinge member I having a body which is curved transversely as shown in Figures 4 and 5, one end portion of said body being deflected and bent inwardly to form an eye or knuckle 2. portion 3 of said body is elongated and formed with a particular sweep adapting it to fit in the longitudinally extending recess A formed in the edge face of the door where it is secured by screws 4 and 4A which pass through countersunk openings 6 formed in the attaching end of the body.

An opening 5 is provided to accommodate a screw driver when applying the screw 4A.

It is noted that a reinforcement plate C is provided and is welded to the backof said recess for the accommodation of screws 4 and 4A.

Opening D is provided where shown in the pillar E of the door frame so as to permit the passage of body I therethrough as indicated.

In Figure 3 it is seen that edge I of the member l is cut diagonally to conform to the vertical curvature of door B, and in this manner it will fit snugly in place against the door with ample rigidity in relation thereto. V

The companion hinge member 8 has a body which is curved transversely to provide a portion 9 adapted to engage the inner'surface of pillar E as shown in Figures 4 and 5 where it is welded to hold it firmly thereto in this relation. Knuckles. H] are formed upon the member 8 in vertical spaced relation to each other and have vertical passages H therethrough so as to permit the passage of a vertically disposed pin l2, and it is understood that the knuckle 2 of the hinge member I will be in axial alignment with knuckles Ill when the hinge is assembled, said pin passing through both the knuckles 2 and Ill.

In view of the curvature of the pillar Ethe recess A sweeps to a greater depth in the center of its length as at l3 in Figure 9, so as to provide proper clearance intermediate the pillar and door at this location thereof.

In Figure 8 it is seen by the center line therein that the hinges are in true vertical and axial alignment with each other, also in the position of Figure 9 center line N indicates the vertical alignment of the hinges, and center line l5 indicates the center of pillar E. In this manner it is clearly understood that the hinges will operate accurately with the proper amount of clearance, and that they provide adequate strength readily The opposite end applicable toany type of door, even to the most massive ones adapted for vehicle bodies of any type or design.

While the invention is primarily designed so as to accommodate vehicle bodies, the same would be as equally advantageous when applied to wall cabinets or the like, or in fact any place where hinged doors are required.

It is obvious in conclusion that the disclosure herewith is merely illustrative in its substance so as to reveal the general principle' of the invention with no limitations upon the design or the proportion thereof consistent with marketable requirements.

Having thus fully described my invention, what I claim as new is: l

1. A hinge for mounting a door for outward swinging movement from a closed position in a door frame at a side of a channelled door jamb to an opened position with its hinged edge face confronting the outer wall of the lamb, said hinge comprising a transversely curved jambengaging member and a door-engaging member pivotally connected at one side with the jambengaging member, the J'amb-engaging member being adapted to be mounted in the channelled jamb against the inner face of said outer wall thereof, and the door engaging member being substantially U-shaped in transverse cross section and together with the jamb engaging member extending conjointly in a spiral path, the door engaging member being adapted to extend from its pivoted side through a side wall of the jamb in overlapping relation to the side edge of the jamb-engaging member opposite the pivotal connection between the members and secured to the side edge face of the door confronting said side wall of the jamb when the door is closed.

2. A hinge comprising a jamb engaging member and a door engaging member pivoted along one side to a side of the jamb engaging member, said members being curved transversely and having their lines of curvature extending conjointly in a spiral path with the jamb engaging member disposed between side portions of the door engaging member whereby the door engaging I, member is disposed in straddling relation to the jamb engaging member and may have swinging movement about the jamb engaging member transversely thereof.
